HD, thanks for your thoughts. This motor has HEI ignition and I agree with you, I think it's an ignition problem. I've replaced everything in/on the distributor except the module. If the module is bad, won't that keep the motor from running? Or, will it still run, but perhaps with problems? If this continues, I think I'll just buy a new high performance distributor with a high output coil. When I put fresh plugs in this thing, it runs great! Just can't keep it running for very long! Let me know what you think about that module and perhaps I'll replace that. If it's a go or no go on the module, I'll just get that new distributor. Thanks again for your interest.
